NCERT Solutions for class 10 Science provided herein are designed by our subject matter experts in a simple and precise manner. It covers answers to all the in between exercises and exercises are given at the end of the chapter. The solutions are provided to clarify the concept of Chemical Reactions and Equations by correlating and thus learning a large variety of chemical reactions taking place around us.

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. The first chemical equation was diagrammed by Jean Beguin in A chemical equation consists of the chemical formulas of the reactants the starting substances and the chemical formula of the products substances formed in the chemical reaction.

Chemical Reactions and Equations Class 10 Notes

Chemical reactions- The transformation of chemical substance into a new chemical substance by making and breaking of bonds between different atoms is known as Chemical Reaction. Signs of a chemical reaction- These factors denote that a chemical reaction has taken place- change of state of substance, change of color of substance, evolution of heat, absorption of heat, evolution of gas and evolution of light. Chemical Equation: The representation of chemical reaction by means of symbols of substances in the form of formulae is called chemical equation. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both left and right sides of the reaction. To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products.
